The relevance of the research is based on the need to enhance the efficiency of geophysical work in the search for zones of sulfide mineralization in the Northwestern Balkhash region, Kazakhstan. The aim of the study is to analyze, summarize and interpret geological and geophysical materials in order to identify promising areas. A comprehensive set of geological and geophysical methods has been applied, including high-precision gravity and magnetic surveys as well as electrical exploration. As a result of 2.5D volume modeling, taking into account various prerequisites and signs of mineralization, we have identified geological and geophysical criteria for detecting gold mineralization. It has been found that ore mineralization is associated with two types of deposits: terrigenous deposits of carbonates and terrigenous rock masses of the Famennian stage of the Upper Devonian. Geophysical criteria for distinguishing ore zones have been defined for these areas. It is found that non-ore areas show a widespread increase in all parameters of geophysical fields. The conducted research allows forecasting supplementary gold mineralization zones, facilitating future geological exploration for gold and associated metals. © 2025, Ore and Metals Publishing house

To improve the accuracy of lithotype classification and reduce uncertainty in hydrocarbon prospecting predictions under conditions of weak contrast in the elastic properties of reservoirs and the surrounding rock by testing a probabilistic approach to seismic data interpretation. Methodology. The study applies a technological approach that includes: 1. Constructing probability distribution functions for lithotypes based on lithological trend data from wells. 2. Using inversion to create cubes of elastic properties and their further analysis using Bayes’ principle. 3. Lithotype classification based on the probabilistic approach by aligning inversion data with probability distributions. Findings. High-resolution seismic data processing was carried out successfully, which ensured their high resolution. Elastic property volumes were obtained and used to assess the probability of various lithotypes. The Bayesian approach to lithotype classification was implemented, demonstrating improved interpretation accuracy in conditions of low elastic property contrast. Promising structures were identified, confirming the effectiveness of the proposed approach in complex geological settings. Originality. A probabilistic method for seismic data analysis was tested, based on the integration of probability distribution functions and inversion data. This methodology allows for accounting for lithological variability and uncertainties during interpretation, representing a novel approach for conditions of low elastic property contrast. Practical value. The developed methodology can be applied in hydrocarbon exploration and field development when reservoir and host rock physical properties exhibit weak contrast. It helps reduce geological risks, optimize drilling site selection, and enhance the economic efficiency of geological exploration

Asphalt-resin-paraffin deposits (ARPD) are a complex dispersed system formed by substances that have separated from the oil phase according to various signs. The sediments include asphaltenes, resins, paraffins, liquid hydrocarbons, mechanical impurities and water. In conditions of intensive deposition of ARPD, normal operation of wells is impossible without carrying out work using dewaxing equipment. The purpose of the treatment is the use of chemical reagents in the composition of the emulsion to affect the bottom-hole zone of the well formation and to remove ASF from underground equipment (UE). The objects of application of this technology are producing wells with decreasing current productivity due to the loss of ARPD. The applied technology should ensure the removal of deposits from the bottom-hole zone (BHZ) of the formation and thereby increase the productivity of the well. The article describes the development and testing of a nitrite composition to increase well productivity. The substantiation of scientific, technical and economic necessity for developing a composition that provides not only a high degree of washing of pore channels, but also a sufficiently high temperature of the process due to the use of the most economical method, i.e. exothermic reaction, is proposed. The paper develops a technology for using emulsions. The results of treating the bottomhole zone of production wells at the Uzen field with an emulsion based on natural gasoline and ammonium nitrite are presented. © 2025 International Multidisciplinary Scientific Geoconference.
